A work tool or a wear member includes a working portion or a wear portion, a hollow portion that further defines a lock receiving aperture defining an axis of rotation, a radial direction, and a circumferential direction. The axis of rotation is transverse to the direction of assembly of work tool or wear member as the member is slid over a nose portion of a tool adaptor or the like. The axis of rotation is spaced away from the direction the pin receiving thru-hole extends a predetermined distance measured along the direction of assembly.
